Gill net fishery in inner Ragay gulf and some aspects of the biology of Liza subviridis, Therapon jarbua and Gerris filamentosus
1986
De los Reyes, M.R.
A nine-month study was conducted in inner Ragay Gulf to describe the present gill net fishery. A total 298.9 tons of food fish species were caught using the bottom-set gill net during the sampling period and an annual catch of the fishery was estimated at about 544.4 tons in 1985. The catch composition, seasonality and relative abundance and catch per unit effort of the fishery were discussed. The taxonomy, fishery, size composition, length-weight relationship, sex ratio and length at first maturity for the selected species (Liza subviridis, Therapon jarbua and Gerris filamentosus) were noted. Observations on experimental trammel netting in inner Ragay Gulf were also discussed.
